`SECTION Polyradices G A Fischer, Seider and Cribb 2007

TYPE: Bulbophyllum petrae G.A.Fisch., Sieder & P.J.Cribb 2007

Epiphytes with membraneous, persistent rhizome scales and densely clustered, bilaterally flattened pseudobulbs carrying a single, coriaceous leaf that blooms on a synanthous, peduncle pendent, scattered, few flowered inflorescence with shorter than the resupinate flowers floral bracts. The petals are finely papillose on the margins and the lip is the same on the underside. The anther has a protrusion that is taller than the anterior margin.

This is a monotypic section confined to Madagascar and occuring in lower montane forests at elevations up to 1400 meters.

Entries below with an asterix are listed in publications by J J Vermeullen etal.[2014/15] and so are more likely correct than ones without. Species with a question mark in front, seem to me to not conform and so please use with caution. If a sectional name has a "`" in front then it is a complete section with all the known species represented.
